Application:
Tenofovir Alafenamide Hemifumarate (TAF, GS-7340 hemifumarate), CAS 1392275-56-7, is a nucleotide reverse transcriptase inhibitor (NRTIs) and a novel prodrug of Tenofovir (TFV). By blocking reverse transcriptase, TAF prevent HIV from multiplying and can reduce the amount of HIV in the body. Tenofovir alafenamide is a prodrug, which means that it is an inactive drug. In the body, tenofovir alafenamide is converted to Tenofovir diphosphate (TFV-DP). Tenofovir Alafenamide Fumarate was approved in November 2015 for treatment of HIV-1.
